Alignment of the central galaxies with the environment
Facundo Rodriguez, Manuel Merchán, M. Celeste Artale
In this work, we combine ellipticity and major axis position angle measurements from the Sloan Digital Sky Server Data Release 16 (SDSS DR16) with the group finder algorithm of Rod…
Subhaloes gone Notts: Subhaloes as tracers of the dark matter halo shape
Kai Hoffmann, Susana Planelles, Enrique Gaztanaga +14
We study the shapes of subhalo distributions from four dark-matter-only simulations of Milky Way type haloes. Comparing the shapes derived from the subhalo distributions at high re…
Structure Finding in Cosmological Simulations: The State of Affairs
Alexander Knebe, Frazer R. Pearce, Hanni Lux +32
The ever increasing size and complexity of data coming from simulations of cosmic structure formation demands equally sophisticated tools for their analysis. During the past decade…
The Relation Between Halo Shape, Velocity Dispersion and Formation Time
C. Ragone-Figueroa, M. Plionis, M. Merchan +2
We use dark matter haloes identified in the MareNostrum Universe and galaxy groups identified in the Sloan Data Release 7 galaxy catalogue, to study the relation between halo shape…
On the luminosity function of galaxies in groups in the Sloan Digital Sky Survey
Ariel Zandivarez, Hector J. Martinez, Manuel E. Merchan
Using galaxy groups identified in the Fourth Data Release of the Sloan Digital Sky Survey (SDSS), we compute the luminosity function for several subsamples of galaxies in groups. I…
Shapes of clusters and groups of galaxies: Comparison of model predictions with observations
D. J. Paz, D. G. Lambas, N. Padilla +1
We study the properties of the 3-dimensional and projected shapes of haloes using high resolution numerical simulations and observational data where the latter comes from the 2PIGG…
